FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 379,458, dated March 13, 1888,

Application filed July Q2, 18E7. Serial No. 245,019. (No model.)

.To @ZZ whom it may concern:

Be it known that l, WILLIAM C. GHoLsoN, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Fence-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1o it appertains to make and use the same.

My invention relates to machines for making wire fences of the character in which warning plates or slats are woven into twisted wire. One kind of such warning-plates and their position in a wire fence is illustrated in my patent, N o. 353,129, of November 28, 1886.

The object of my invention is to dispense with the complicated mechanism heretofore used in many machines and to construct a simzo ple, easilyfo-perated, and efcient machine for the purposes mentioned.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is afront elevation; Fig. 2, aplan;

Fig. 3, a section on line :c :o of Fig. 1, and Fig- 4 a detail.

Referring to the drawings, the frame of the machine is composed of four longitudinal bars, A A A A', supported between four upright bars, B B B B, and mounted upon uprights C, or other suitable support. Vithin this frame are placed two racks, D D', an upper and a lower one, each of which isseeured to and between two bars, E. The back of each rack-bar extends beyond the bars E and between the bars A. The racks and their carrying-bars E are adapted to be slid in opposite directions between the bars A, as hereinafter described.

F F are cog-wheels placed between the racks and meshing therewith. These wheels have no axles, but are provided with two or more holes, g, each adapted to receive a separate strand of wire. The racks are so placed between the bars E that the bases of their teeth are below the bars, so that the cogs F, when engaging with the racks, are held upon the frame and are prevented from falling out.

H is a cog-wheel mounted in a frame, I, on

5o the machine, connected with a suitable shaft and crank to be operated by hand or other power, and engaging with the racks to give the same alternate reciprocating motion.

L L represent wires proceeding from reels (not shown) extending through tension-plates N on bars N, and each wire passed through a' hole, g, in the wheels F. The wheels F are to be placed a distance apart on the racks in accordance with the distance apart it is desired to twist the wire on each plate or slat.

The operation of the machine is as follows: The wires being placed in position and extending through the holes g in the wheels F (the holes in the said wheels to be increased with the number of wires, as desired) and connected to a drawing reel or drum of ordinary form, (not shown,) the crank is turned, which moves the rack in opposite directions, while the cogwheels remain and rotate in their respective positions. A first or preliminary twistsuch 7C as p, for instance-is given. Then the machine is stopped and a slat or warning-plate is placed on the wires between the strands, the motion of the machine reversed, and a twist formed on the opposite side of the plate or slat, another plate or slat is inserted, and the operation is repeated. Thus the order of twisting will be reversed between each plate or slat, and the wire between the tension-bars andthe cogs will twist and untwist with the opposite revo- 8o lution of the wheels while the operation of weaving proceeds.

The number of wire-twisting wheels F may be varied to suit the number of slats or plates to be operated on at the saine time. The racks must be of sufficient length to permit of the revolution of the cogs a sufficient number of times to give the desired amount of twist.

The frame and rack-bars may be extended to any desired length, so as to make the fenc- 9o ing at many points throughout the extent of a long room orbuilding. As the wheels twisting the wire carry only their own weight, the force necessary to turn the wheel operating the racks, and at great speed, is not great; but other Vmethods of operating the saine than the one I have illustrated may be employed. For instance, shafting' may be applied at the opposite ends of the racks to give each its opposite reciprocating motion.

IOO

of the racks, the sliding bars in which said racks are secured, the stationary bars between which said sliding bars are moved, the aXleless cog-Wheels held between and engaging With said racks, and suitable mechanism for oper- 2o ating said racks and their supporting-bars simultaneously in opposite directions, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.

WILLIAM C. GHOLSQN.

The principle of my invention may be adapted to twisting other material than wire and for other purposes than Weaving therewith slats and plates.

5 Having thus described my invention, what I claim is- 1. The combination, in a suitable frame, of the racks adapted to move simultaneously in opposite directions and independently of the 1o supportingfranie, and the twisting-wheels engaging with said racks and provided with holes through which the twisting material is carried, substantially as and for the purpose described.
